CPI-644

CPI-644 is a selective EP300/CBP bromodomain inhibitor, with an IC₅₀ of 0.18 µM against the CBP bromodomain. CPI-644 reduces the proportion of FOXP3⁺cells and downregulates the expression of LAG-3, CTLA-4 and PD-1. CPI-644 can be used in cancer-related research.

In Vitro

CPI-644 potently and selectively inhibits the purified CBP bromodomain in AlphaLISA peptide competition assays, with an IC₅₀ of 0.18 μM^[1].
CPI-644 binds tightly to the purified CBP bromodomain, with a K_d value of 0.084 μM measured by ITC^[1].
CPI-644 inhibits the cellular interaction between the bromodomains of CBP and EP300 and histone H3.3 in HEK293 cells, with EC₅₀ values of 0.53 μM and 0.36 μM, respectively^[1].
CPI-644 potently inhibits the differentiation of naive human CD4⁺CD45RA⁺ T cells into FOXP3⁺ Treg, with an IC₅₀ of 1.8 μM^[1].
CPI-644 dose-dependently reduces the expression of Treg inhibitory markers LAG-3, CTLA-4 and PD-1 in in vitro differentiated regulatory T cells (Treg), with EC₅₀ values of 0.9 μM, 1.8 μM and 4.3 μM, respectively^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
